Bring a pot of water to a boil over high heat and pour 2/3 cup of water over 2 rooibos tea bags. Let it steep for 5-10 minutes, until dark.
Meanwhile, if using a handheld milk frother, warm tea in a small pot over medium heat or microwave for about 20-30 seconds. Use the device to froth the milk until light and fluffy - transforming 1/3 cup of milk to about 1 cup of frothed milk.
If using a latte machine, pour milk into a steel cup and angle the cup, moving it in a circular pattern, till milk is frothed and warmed through.
At the same time, pour the frothed milk and steeped tea into a mug, finishing the top with the foam from the milk. Serve warm. Taste and add honey as needed.
Notes
If using loose leaf rooibos tea use 3 teaspoons.
If using a French press, pour warm milk into the bottom and press up and down till milk is light and frothy.
If you prefer a more milk-heavy latte, you can use 1/2 rooibos and 1/2 frothed milk, however this will decrease the flavor of the rooibos. You may need to add another tea bag or steep for longer for a stronger flavor.
I find using oat milk, 2%, and whole milk to yield the best flavor and texture. If using oat milk, you most likely won't need to add honey to sweeten.
For an extra flavor boost, sprinkle with cinnamon on top.
